As the celebrations memorializing the 10th anniversary of 9/11 became echoes, the last of 85 wrongful-death lawsuits stemming from the attacks were resolved Monday, court records showed.

"This is the first time in 10 years not to be in fighting mode," said Mike Bavis, who lost his 31-year-old twin brother Mark when United Airlines Flight 175 became the second plane to pierce the World Trade Center on September 11, 2001.

The Bavis family filed a "gross negligence" lawsuit in 2002 against United and Huntleigh USA, the security company for United Airlines at Logan International Airport in Boston, where the flight originated.

Family attorney Donald A. Migliori said the family hoped to get some accountability for the tragedy.

The family originally opted not to accept payment from the Victims Compensation Fund, but had a change of heart after a court decision this month put the burden of proof on the family and not on the airline and security firm.

The resolution of the case involved compensation, but details were not released.

United Airlines issued a statement saying that "the tragic events of 9/11 impacted all of us, and we are pleased to resolve this case."

Huntleigh's attorney didn't respond to CNN's request for comment.

"The family of Mark Bavis feels that achieved many of their goals," Migliori said. "They were able to ask target questions under oath, and got important answers they were looking for."
